The use of artificial intelligence (AI) is becoming increasingly prevalent across various industries, and the pharmaceutical industry is no exception. Incorporating AI into Drug Discovery and development has the potential to greatly revolutionize patient experiences and outcomes.

In the past, advances in computational technology have allowed for greater exploration of the vast chemical space. Computer-aided design and drafting, or in silico approaches, have been used to enhance traditional Drug discovery methods by reducing the time and cost of drug development. However, the success rates of these methods remain low, with only 10% of candidates reaching clinical trials.

To address this issue, AI has shown promise in enhancing in silico methods. By analyzing and exploring large amounts of biomedical data, AI can gain a better understanding of the biological mechanisms of diseases. This enables AI to map disease pathways and identify novel proteins and genes that can be targeted for treatment. AI can also predict three-dimensional structures of targets and accelerate the design of appropriate drugs.

Once promising lead compounds have been identified, AI can assist in prioritizing candidate drugs for further assessment. AI can also be used in virtual screening, de novo drug design, drug repurposing, and identification of treatment response biomarkers. These AI algorithms have the potential to significantly reduce the time and cost of bringing a drug to market.

In recent years, there has been a notable increase in AI activity in drug discovery. Start-ups in this field have emerged, and there have been numerous drug discovery partnerships and high levels of investment. Notable milestones include AbSci’s creation of de novo antibodies in silico and Insilico Medicine’s development of a small molecule inhibitor treatment for idiopathic pulmonary fibrosis.

Despite these advancements, most drugs developed using AI are still in the preclinical or discovery stages. It may take several more years before an AI-based therapy is approved. AI faces challenges such as data quality, ensuring drug safety and efficacy, gaining buy-in from the scientific community, and issues surrounding intellectual property rights.

Nevertheless, AI has the potential to greatly speed up and reduce the costs of drug discovery processes. This could be transformative for patients, medical providers, and the pharmaceutical sector as a whole.
